Terrace on steel beams
Steel girders offer the advantage that, as a rule, everything should already be “in the water” here, i.e. no leveling of the surface is necessary. To ensure that steel and wood or steel and aluminum do not cause any noise later on, the supports should be covered with patio pads at certain points or with a rubber granulate roller over their entire length.
On many balconies and roofs, the steel beams were welded at intervals that did not match the desired laying direction of the decking. Only with a relatively narrow grid of 50cm or less can the construction timber run parallel to the steel girders. For larger distances, the construction timbers must run across the beams. If you then want to change the laying direction of the terrace floorboards, counter battens are necessary, but care must be taken to ensure that the railing is not too low later on.
